TL;DR: The European Aerosol Research Lidar Network (EARLINET) as mentioned in this paper was founded as a research project for establishing a quantitative, comprehensive, and statistically significant database for the horizontal, vertical, and tempo-ral distribution of aerosols on a continental scale.

TL;DR: In this article, measurements of aerosol optical properties and aerosol number size distribution obtained during the period from December 2005 to November 2007 at Granada, an urban site in south-eastern Spain, are analyzed.

TL;DR: In this paper, the variations of the ratio of photosynthetically-active radiation to broadband solar radiation with sky conditions are described by means of variables that could be accessible in common radiometric networks.

TL;DR: An in-house sky imager system for the purpose of cloud cover estimation and characterization is developed and the classification algorithm is validated on two levels: image level, using the cloud observations included in the METAR register performed at the closest meteorological station, and pixel level, determining whether the final classification is correct.

TL;DR: In this paper, two data sets registered in two locations in Spain were used to study the necessary correction factor for diffuse irradiance measurements obtained by means of shadowband and developed two different correction models, using twothirds of the hourly data set, while the remaining one-third and the whole 5-minute data set have been used for validation purposes.
